CULTIVATOR ATTACHMENT. i

To all fwwm it may concern.' l

Be it known that I, EARL STEWART, a citizen of the United States, and aresident of Des Moines, in the county of Polk and State of Iowa, haveinvented a certain new and useful Cultivator Attachment, of which thefollowing is a specification. v

The object of my invention is to provide a cultivating tool of simpleand inexpensive construction, adapted to be mounted o'n any' ordinarycultivator frame.

More particularly it is my object vto pro-4 vide a blade adapted totravel on the, ground on a diagonal line for cutting just under thesurface of the ground for certain kinds of cultivation, particularly indry form.

Extending upwardly and rearwardly from the blade are a plurality ofarms, partsl V of the arms at the end having a crimped wire extension onthem for carrying over weeds and vines and the like, while the remainingarms having a cutter blade of peculiar form.

The blade has a long supporting arm on which is rotatably mounted acutting wheel having notches so arranged as to cut weeds, vines and thelike with a shearing cut.

With these and other objects in view my invention consists in theconstruction, arrangement and combination of the various parts of thedevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which:

Figure 1 shows top or plan View of the cultivating tool embodying myinvention.

Fig. 2 shows a side elevation of the same, parts being broken away.

Fig. 3 shows a detail, sectional view of one of the cutter devices onthe arms.

Fig. 4e shows a side elevation of one of the crimped wire members forraising the corn and shaking the dirt out from the weeds.

Fig. 5 shows a vertical, sectional view through the axle of the cutterwheel; and

.Fig 6 shows a front elevation of the device.

In Figs. 1 and 6 part of the cutter blades on the arms are omitted.

In the accompanying drawings, I have used the reference numeral 10 toindicate generally a broad flat blade having the sharp edge 11, which isdesigned to travel on a diagonal line just underneath the surface of theground 12,

specification of Letters Patent. f lllatented'kpr. 22, 1919. Appueetienmed october 14, 191s. serial' ne. 258,674. 4 'i vas illustrated in Fig.2., v A j At the rearA edge of the blade l0 is a plurality ofupwardlyand rearwardly extending arms 13. The two Quterjarms onrone blade on the4side designed to be next to the corn or the like, are-extended upwardlyat a sharper angle and higher than the` other arms, as indicated at13a.y

Secured to the arms 13a-and extending upwardly and rearwardly arecrimped wires 14 having wave form.y y l Secured to the rear ends of thearms; 13 are upwardlyand rearwardly extendingcutter bars w15, havingspaced upwardly extend#v Q in cutting edges 16. Y

ecured to the central portion of the blade 10 is a supporting arm 17,5which extends upwardly and rearwardly and has at its upper end anelongated slot 18 through which are extended bolts 19 by which thesupporting arm is secured to an arm 20 of a cultivator.

Rotatably mounted on the frame 17 is a cutting wheel 21 having aplurality of notches 22, one edge of each notched portion beingsharpened as at 23, so that the sharp edge 23 of each notch will cutweeds, or especially morning glories with a shearing motion with respectto the arm 17.

The edges 23 are arranged almost radially of the cutting wheel.

In the practical use of my improved cultivating tool, the blade 10travels under the surface of the ground making a shallow cut,

and cutting olf the weeds with a shaving or shearing movement. The weedsthen travel upwardly and rearwardly from the arms 13 and 13a.

rThe plants to be cultivated, such as corn, will be raised by the arms13L and the wires 14 and will be shaken as they travel over the ground13 for dislodging any dirt, so thatl the plants will thereafter extenduprig t.

The weeds travel upwardly from the arms 13, and thence over the cutterbars 15 and are cut to pieces on the edges 16, and are also shaken asthey travel from the edges 16 for freeing them from dirt, so that whenthey drop on the ground they will be exposed to the sun and will dry.

Some changes may be made in the construction and arrangement of theparts of my improved device without departing from l the essentialfeatures and Apurposes of my invention, and it is my intention to coverby this application, anymodied formsoit' structure or use of mechanicalequivalent which may be reasonably included within the scope of myclaims.
